The answer is 38.5 sq.m. area of the sector= (90*3.14*7*7)/360

Thanks!

The correct answer is 38.5. this can be found out using area of sector formula=pi*R^2*theta/360=pi*7^2*90/360=38.5sqm

since the goat is tied to 7m long rope it graze the circularly..the area of circle is 3.14*r*r...the radius is 7m here and so area grazed will b 3.14*7*7..which is equal to144.86 m-square

Since the goat is tied to one corner of a square plot, so it can graze only ¼ th of the circle produced with 7 meter rope as radius.
so area covered = ((22/7)*7*7)/4 = 38.5 square meter.

Formulae is O / 360*22/7*r*r
Since it is square its obvious that O is 90.....we get 38.5

As the goat is tied at one corner so it can only graze 1/4 area of the circle having radius 7m.

so the required ans is 1/4 (area of circle) = 38.5
